Abstract :
In the field of OFDM technology, it is known that the phase rotations and reverse of a block quaternary codeword give the same peak-to-mean-envelope-power-ratio (PMEPR) as that of the original word. In this paper, we show that there exist the third and fourth operations that also result in the same PMEPR.
